@JeffBerntsen no KVM - monitor, kb, mouse directly connected. I did also unplug all 3 and booted up but it didn't change anything, after waiting a few minutes I plugged the keyboard back in and had to make a selection to get it to load XCP-NG.

@hansve You're welcome.

@plaidypus I think the real question you should ask yourself is: do your workloads actually need to worry about the extra latency from a NUMA node span?

If you're not doing something pretty darn extreme here, I don't think it really will matter. There has been lots of talk for decades about this on VMware, but I just don't think it's that relevant anymore. Latency between sockets has gotten pretty good, so unless it's some really special workload, I don't think you should worry about this much.

The best way to validate is to just test and see how things go.

But do you have info on what workload this VM will be running?

@apz I see. Thanks.

@R2rho yeah, there are Supermicro systems with AM5 which can handle a decent amount of load, like based on the h13sae-mf, like:

(with less depth)

Seem to be stable, but we have a small issue regarding onboard graphics ATM:

You should start by checking the logs. https://docs.xcp-ng.org/troubleshooting/log-files/

Thanks for letting us know, and I'm happy you have thing working nicely now.
I think to mark this as resolved you need to convert your original post as a question, and it can then be marked as resolved. I actually cannot do it myself, I think only a few people have the permission to do it for others at Vates.

Can you try on latest release channel and see if you still have the error? Thanks!

Enjoy XO & XCP-ng then 🙂

@olivierlambert

I resolved it, logged in the XCP-ng console and set the NTP servers to default. All good now.
Thanks

I have yet to successfully reboot a host from XO. I have tools installed on three out of four VM. I try shutting down the VM without tools, then issue reboot host in XO GUI. Get warning:
Some VMs cannot be migrated without first rebooting this host. Please try force reboot.

Is this a setting perhaps?

I'm always needing to shutdown all VMs before I can reboot the host. It is a single host environment, so there will never be an available server to migrate VMs to.

Rebooting in XSCONSOLE causes the host to be unavailable in XO. I have to remove then add the host back in XO.

Can anyone shed light as to what I'm doing wrong?

Do I just need to always run the following after a reboot?
xe host-enable host=xxxx

Preferably after, since the PV drivers contain some VM-specific settings that may be wiped by Sysprep.

FWIW...having the same issue with Server 2025.

@dinhngtu said in Issues with XCP-ng Windows PV Tools 9.0.9000.0 Testsign Pre-release:

With 9.0.9000.0, you could sometimes run into this issue if you reboot too early after installing. This will also be fixed in the next release.

I just did two more tests and the boot-up failure happened both times. On the last test I waited some time (like 30 to 60 sec) after the driver installation before rebooting (using Windows restart from the start menu). Even though I waited before rebooting I still encountered the boot-up problem:

Windows is spinning on this screen and doesn't finish booting:

(In regards to uninstalling XenServer / Citrix Tools)

I tested uninstalling XenServer tools v9.4.0 on Windows and it seems to uninstall cleanly. (the xcp-ng docs mention there have been problems uninstalling everything cleanly in the past)

Also since XenServer tools v9.3.1 there is a new purge function:

uninstall.exe purge - (9.3.1 and later) Resets the VM to a clean state as it was before any part of the XenServer VM Tools were installed.

What does the purge option remove?

I wasn't aware of this plugin even existing (thanks for the discovery). I'm not sure it's really maintained, but we have a clear goal of getting one officially maintained anyway.

@olivierlambert

Which one, powershell or WAC. They are kind of one in the same when you look at how WAC makes the calls to do the work, there's a button to reveal the powershell behind the button clicks so you might be able to get both at once.

But WAC draws nice graphs and gives us a GUI to get the work done. Yes I know, real Admins don't use GUI. Whatever, AI will eat our jobs anyway, just trying to stick it out another 9 years at this point.

When I get time, I'll still probably take a swing at this task for WAC, because to me this would be valuable. Big learning curve though.

Now if MS would finally add Group Policy to WAC and fix some of the DHCP and DNS features that are still in preview...

@dinhngtu Ah thank you! Idk why I couldn't find that on my own, I searched for a while.

According to the documentation, you only need xfsprogs.
